LP2981
Micropower 100 mA Ultra Low-Dropout Regulator
General Description
The LP2981 is a 100 mA, fixed-output voltage regulator de-
signed
battery-powered applications.
Using an optimized VIP
cess, the LP2981 delivers unequaled performance in all
specifications critical to battery-powered designs:
Dropout Voltage. Typically 200 mV
7 mV
Ground Pin Current. Typically 600 µA
80 µA
Sleep Mode. Less than 1 µA quiescent current when ON/
OFF pin is pulled low.
Smallest Possible Size. SOT-23and micro SMD packages
use an absolute minimum board space.
Precision Output. 0.75% tolerance output voltages avail-
able (A grade).
Eleven voltage options, from 2.5V to 5.0V, are available as
standard products.
